The singer also sasses the Southwest Airlines flight attendant who repeatedly requested his cooperation.

Armstrong and a companion were on their way to Burbank, Calif. from Oakland, Calif. when the incident occurred. Passengers were preparing for departure when a flight attendant approached the musician -- who was waiting to put his bag in an overhead compartment -- and asked him to pull his pants up, according to an ABC news producer who was on the flight.

Armstrong responded, "Don't you have better things to do than worry about that?" The flight attendant then repeated the request and threatened to have Armstrong taken off the plane if he didn't comply.

He was removed from the flight after answering, "I'm just trying to get to my f**king seat."

The singer tweeted after from the airport, "Just got kicked off a southwest flight because my pants sagged too low! What the f**k? No joke!"

He took the next available flight to L.A.

Southwest said in a statement, "As soon as we became aware of what had happened, we reached out to apologize for this Customer's experience. He elected to take the next flight. We followed up with this Customer and involved Employees to get more details and, in our latest conversations, understand from the Customer the situation was resolved to his satisfaction."
